The first component required for ecological speciation is a source of divergent selection. Three ecological causes have been recognized (Schluter 2000, 2001; Kirkpatrick Ravigné 2002).Although they are not fully independent and distinguishing between them may not be easy, their separate treatment is useful because it highlights the diversity of ways ...

Speciation Wikipedia Speciation is the evolutionary process by which populations evolve to become distinct species.The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to ghjnbganagenesis, phyletic evolution within lineages. Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book On the Origin of Species. Linking the emergence of fungal plant diseases with ...

The study of ecological speciation has come a long way in Naisbit et al. 2003), but also suggest the possibility of non recent years. Mechanisms have been clarified, specific ecological speciation of parallel evolving populations due to predictions have been recognized, and much data has been the fixation of incompatible alleles. Is ecological speciation a major trend in aphids? Insights ... Ecological speciation occurs when a transition in resource and or habitat within ancestral species triggers gene flow interruption and the formation of new sister spe cies [1,2]. This process can occur in allopatry (e.g. [3]) but is also supposed to permit sympatric speciation [4 6]. In the past decade, the role of ecological speciation in the di ANDEAN SPECIATION AND and VICARIANCE IN NEOTROPICAL Jason ... speciation suggests that competition among popula tions led to subsequent ecological niche divergence, whereas allopatric speciation invoked a spatial barrier and not necessarily any ecological niche separation (Mayr, 1963). This is applicable not only to extant sister species pairs, but also to deeper clades in the Ecological speciation Wikipedia Ecological speciation is the process by which ecologically based divergent selection between different environments leads to the creation of reproductive barriers between populations. This is often the result of selection over traits which are genetically correlated to reproductive isolation, thus speciation occurs as a by product of adaptive divergence. PhD position in the genomic basis of ecological speciation ... I both species, specialization on noni was accompanied by the evolution of reproductive isolation, hence representing a unique case of parallel ecological speciation. The thesis aims at combining different approaches of population genomics, chemical ecology and functional genetics to identify the genomic basis of this convergent specialization. Evidence for Ecological Speciation and Its Alternative ... Ecological Speciation. Evidence for ecological speciation has accumulated from top down studies of adaptation and reproductive isolation [reviewed in (2, 8, 9)]. We now know of many real species that have, at least in part, evolved by divergent natural selection between environments. Ecological Speciation Lessons From Invasive Species Ecological opportunity is the key for speciation and invasion; and it is most often found on young islands. In general there are no traits that presage which exotic species will be the best invaders of natural areas. Thus it would be difficult to predict which traits foster ecological speciation.
